Which two statements are true about Spring Data JPA? (Choose two.)

Question

Options

• Aspring-boot-starter-data-jpa pulls in all necessary dependencies for Spring Data JPA.
• BSpring Data JPA can be only used in combination with Hibernate.
• CThe persistence.xml has to be provided for Spring Data JPA as it is defined in the standard.
• DAuto-configuration creates the needed Beans like DataSource and JpaTransactionManager.
• EScanning of JPA Entities can not be customized.

• A
  85% (23)
• B
  4% (1)
• C
  7% (2)
• E

Explanation

A is correct because spring-boot-starter-data-jpa is a convenience starter POM that bundles Hibernate, Spring Data JPA, and all required transitive dependencies - you add one dependency and you're ready to go. D is correct because Spring Boot's auto-configuration mechanism automatically creates essential beans (DataSource, EntityManagerFactory, JpaTransactionManager) based on classpath detection and application.properties, eliminating boilerplate configuration.

B is wrong - Spring Data JPA is an abstraction layer over JPA (the specification), so it can work with any compliant JPA provider such as EclipseLink or OpenJPA, not just Hibernate. C is wrong - Spring Boot's auto-configuration makes persistence.xml entirely optional; entity scanning and datasource config are handled through @SpringBootApplication and application properties. E is wrong - entity scanning is fully customizable via @EntityScan to specify which packages to scan.

Memory tip: Think of the letters A and D as "Auto-configuration Does everything" - Spring Boot Automatically pulls in dependencies (starter) and Deploys the needed beans, so you write zero infrastructure code.
